Automatic packaging machine for mercury thermometer

Abstract

The invention relates to an automatic packaging machine for a mercury thermometer. The packaging machine comprises a rack, a hopper system, a trough system, a pressing system and a pushing system, wherein the hopper system is fixed on the table of the rack by two supporting plates; a hopper is divided into three parts which are used for holding a housing cover, a thermometer and a housing from left to right in order; the baseplate of the hopper forms certain angle with the horizontal plane, which is more favorable for objects to slide down automatically; the trough system comprises a trough, a substrate, an ejecting cylinder, a linear module and a linear guide track; the pressing system comprises two L-shaped brackets and a cylinder, and the L-shaped brackets are fixed on the table of the rack; and the pushing system comprises a linear module, a servo motor, a pushing needle and a guide plate. The packaging machine uses an intelligent control platform to control the servo motor and carry out stepless speed regulation, the procedures of discharging, pushing and packaging can be controlled preciously, the production efficiency is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of packaging machines, in particular to a packaging machine for automatically packaging mercury thermometers. Background technique [0002] In the production process of mercury thermometers, the packaging of mercury thermometers is the last process. In the field of existing thermometer production, there is no automatic packaging machine for mercury thermometers. It still relies on manual packaging by workers, which is inefficient and labor-intensive. The reason why automation equipment is still blank in this field is mainly due to the following reasons: [0003] 1. The shell cover and shell of the thermometer shell are light in weight, and the shape is an equilateral triangle plastic, which is easy to turn over and fragile during automatic feeding; [0004] 2. The shape of the mercury thermometer is irregular, and it is made of glass, which is easy to be crushed, and it is not easy to realize automatic feeding; [0...
